Embodiment Construction

[0012] An anti-seepage digital printing method, comprising the following steps: fabric pretreatment, drying, spraying a physical adsorbent on the fabric, drying, spraying a physical adsorbent on the entire fabric, drying before printing, inkjet printing, and drying after printing , steamed, washed and dried. The physical adsorbent is calcium carbonate powder liquid or mesoporous silicon dioxide or mesoporous titanium dioxide. In the process of locally spraying physical adsorbent on the fabric, the injection position of the physical adsorbent is the inkjet position of the pattern required by the final product, and the printing nozzle involved in the spraying physical adsorbent and the inkjet printing process is the same nozzle, The physical adsorbent tube and the ink tube are respectively connected in the aforementioned two different processes. In the process of fabric pretreatment, the weight fraction of each component of the pretreatment liquid is: 2% paste A-9, 2% SW-MN-08,...

Abstract

The invention discloses an anti-bleeding digital printing method, which comprises the following steps: fabric pretreatment; drying; local spraying of a physical adsorbent on the fabric; drying; overall spraying of the physical adsorbent on the fabric; drying before printing; inkjet printing; drying after printing; steaming; washing; and drying. According to the principle that the bleeding phenomenon can be reduced by forming a porous surface on the fabric with calcium carbonate or mesoporous silica or mesoporous titania as a physical absorbent, a calcium carbonate powder solution is sprayed according to the printing pattern; the overall fabric is coated with the physical adsorbent; the physical adsorbents which are different in solubility are formed on a printed region and a non-printed region of the fabric, so that the adsorption capacity of the printed region to dye ink is relatively high; and the dye ink can be relatively well prevented from bleeding towards the non-printed region.

Description

technical field [0001] The invention relates to the field of jet printing, in particular to an anti-seepage digital printing method. Background technique [0002] With the overall improvement of today's world economic level, people's demand for clothing, textiles, etc. is becoming more and more individualized and diversified, which has brought a certain positive impact on the traditional textile industry, requiring that the manufacturing field must also be transformed into Multi-variety and small batch production process. The emergence of digital printing technology just meets and adapts to this new market demand. Digital printing technology is the product of the integration of advanced technologies such as precision machinery, computer and optoelectronic integration, and is a major breakthrough in traditional printing technology. As customers' demand for digital printing products of different fabric types, especially digital printing products of high-grade fabrics, is incr...
